When I step on the gas I heat water behind the dash/glovebox. There is no leaks. From reading threads, I understand that it might be air and I need to bleed the cooling system. Can anyone please let me know the proper way to do this. It seems that there is a lot of methods, which is confusing. Please advise of the correct method. I have a 02 DiscoII, 105,000 miles.
Help will be greatly appreciated.

Thanks

Read the rave it is pretty easy. Hope it is air and not blown head gasket. I could type out the procedures but if you download the rave it is a very easy and simple job.

 

Better yet you have been here long enough to know how to use the search bar up top and search for this topic. It comes up about once a month look up water fall sound, how to bleed coolant system and you will find plenty of information about your problem.

 

The easiest way I found was when the engine is cold. loosen the bleeder screw on radiator hose, fill the water/coolant tank ,place your mouth over the inlet hole and blow untill you see the water spert from the radiator hose, tighten screw , top up tank and thats about it .. good luck with that.

 

After you have driven 5 miles or so- you MUST have the engine HOT.

The coolant tank is made to unclip from the cradle it sits in.

Unclip the coolant tank.
RAISE it as high as it will go.

Take the cap off. Take the cap off very slowly.
Bubbles may start coming up.
This can indicate a blown head gasket.

Note - coolant may try to come out.
If it does, stop and wait with the cap just off enough to release pressure.

Keep the tank elevated by stuffing stuff under it - some old
wood or rags.

The cap is now off the tank.
Start the engine
Put heater on HIGH.
Run the engine at 1,200 RPM or so
Run at 1,200 for 8 minutes.

The level of coolant should go DOWN if air is coming out.
This is a dynamic bleed method and gets out ALL the small bubbles.

After 8 minutes, the coolant level should have lowered as air came out.
Put in coolant to get the level to the hot line

Replace the cap.
Put the bottle back in the cradle.

Now, drive around and that waterfall sound should be gone.

I don't mess with that T.
Reason - I don't feel it works well.
And the T can break with too much handling as some of them
are defective from the factory and brittle.

No one approves of my method
But, it works for me.

I don't do it like the RAVE Book.

 

Horrible horrible horrible way to bleed air from coolant system you are trying to take air away not ad air.

 

I call that blow fish method - "the whale".
Had not heard of that one yet..
May work somewhat.
Depending on where the bubbles are.
I would try it while parked on a huge HILL nose up.

 

Lets get the "whale" posted up as a sticky (new proper way to bleed cooling system) forget the "rave" this has got to be the way to go

 

Are you constantly adding fluid while it is running and going DOWN?

Hot line? I don't see that on my tank.

 

your big question should be if "There is no leaks" where did all that coolant go?
